Hi, For me, I put a hidden session variable that is set when the form loads. I then test for it before emailing. If it does not exist I do not send the email. If it does exist I send the email and kill session. I usually do my forms as 2 parts one form page and one processing page.
Since the variable is hidden in the session it forces someone to at least use the first form page. Although it is not fool proof. I guess someone could use cURL to get around that.
